Plz me if you're smart answer this plz

6

Step-by-step explanation:

The rate at which Darin can mow a lawn can be found by dividing the number of lawns mowed by the time in hours to mow that number.

Rate

= (Lawns mowed) / (Time)

= 90/45h

= 2/h

It takes Darin's service to mow 2 lawns one hour.

Time = 0.5(number of lawns)

Time = 0.5(12)

Time = 6

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
